The code belowfixes the problem, but changes all the dates to current. It would be nice to have the original time/date stamp for sorting and looking at the family timeline.Google search brings me to Stackoverflow (ffmpeg keep original file date?) They us PowerShell, I don't know how to use it and I don't think it will work because in the example the PS operation is done after the FFmpeg conversion is done. FFmpeg in the copy sets the creation time, last modified, and last access to the time/date the FFmpeg was run.
